Phase One	Chrome-tanned substrate	Raw hides are used after depilation and soaking in ash Chromium salts The main tanning process is carried out, resulting in a “blue wet leather” state	Endowed with leather Soft and full The tactile feel, as well as Excellent tear resistance and heat resistance
Phase Two	Veg-tan Tanned again	Blue wet leather is retanned using specific bark extracts (such as shame leather) and natural agents。	Added leather Firmness And Elasticity making it easier to handle during subsequent cutting and sewing, and preparing for oil absorption
Stage three	Soak in hot oil	The leather is placed in a steam drum and mixed at high temperature Food-grade tallow, cosmetic-grade beeswax 、 A mixture of natural fats (such as whale oil) is saturated for soaking	This is Chromexcel The soul process 。 The oils give the leather its unique character Waxy feel 、 Waterproof And famous “ The effect of ‘pulling the change’
Stage Four	Dry dyeing	The leather is air-dried (not oven-dried) to shrink and tighten, then hand-applied multiple times by artisans Aniline dyes Apply color, then finish with a spray coat Authentic beef hoof fat	Air drying forms a compact grain surface similar to a calf; Hand-coloring ensures deep and layered colors; Beef hoof oil is used as a protective agent for the coating

Analysis of Characteristics and Advantages and Disadvantages

Signature feature: pull transformation effect

Lift it from the back of the leather with your finger, and you’ll see the color lighten. This is because the wax inside the leather is temporarily pushed apart, causing changes in light refraction. As you wear it, the wax and oil redistribute or fade, which is why leather ages and develops a ‘tea core’ effect.

Physical and chemical properties

Soft means comfortable : Feels excellent when leaving the factory, almost no break-in period, and does not cause foot rubbing.

      Natural waterproofing : The grease fills the gaps between fibers, providing excellent water repellency (note: it is waterproof and splash-resistant, not waterproof soaking).

      Rapid aging : It’s easy to get scratches and scratches, which is both a disadvantage and a plus. As time passes, these small marks merge into a unique “patina of time.”

      Stretchability : Due to rich oil content and soft chrome tanning, CXL is purer Veg-tan Leather is more prone to stretching and deformation. If used as a watch strap, a lining layer should be added to prevent stretching.

      Edge handling is difficult : Due to the high oil content, traditional edge banding techniques are difficult to achieve, and repeated grinding can easily cause the edges to “pillage.”

Comprehensive Application Scenarios

Application areas	Specific products	Performance evaluation	Cause analysis
Shoes and boots	Work boots and leather shoes	A selection of classics	Extremely comfortable, almost no break-in required; The pulling effect makes the aging process highly visually appealing 。
Leather jackets and jackets	Motorcycle jacket	An excellent choice	Soft and body-hugging, windproof and water-repellent. Scratches are easily “repaired” by grease or create a unique vintage feel 。
Small leather goods	Wallets, phone cases, watch straps	Use with caution	The texture and scent are premium. However, as a strap, it is prone to stretching and deformation; As a phone case, it is prone to scratches; Because it is not transparent, edge wear may reveal the base color
Belts and load-bearing items	Belts, sashes, and sheaths	Not recommended	Extremely prone to stretching and deformation; Moreover, the chemical composition of chrome tanning agents may corrode metal blades or firearms .
Accessories and miscellaneous items	Dog collar	Good performance	Soft and durable, highly comfortable for pets.

Maintenance Guide

Daily maintenance : Only a horsehair brush is needed to dust and wipe with a finger or a soft cloth to “polish” surface scratches.

Clean : Gently wipe dirty areas with a semi-damp cloth.

Fat supplementation : Because leather itself is full of oils, Avoid over-maintenance 。 Use when the leather feels dry to the touch Pure beef trotter fat Or Naturally solvent-free Leather care oils (avoid products containing silicone oil or petroleum solvents).
